Disseminated Mycobacterium marinum infection in a patient with rheumatoid arthritis receiving infliximab therapy

Abstract

Tumor necrosis factor-alpha inhibitors are important adjunctive therapies for rheumatologic diseases. These agents increase the risk for granulomatous disease. We present a case of a woman with severe rheumatoid arthritis on infliximab who developed multiple nodular skin lesions. Biopsies grew Mycobacterium marinum. New lesions developed through therapy, necessitating surgical debulking.
